Abstract: The title compound, an analogue of hydrolysate of antineoplaston A₁₀(3-phenylacety-lamino-2,6-piperidinedione) was prepared by the condensation of L-glutamine and p-toluenesul-fonic chloride.Its crystal structure was studied by X-ray diffraction analysis.Molecular formula C₁₂H₁₆N₂O₅S, M_r=300.31.Space group P2₁, α=1.2784(4) nm, 6=0.5240(1) nm, c=2.1356(4) nm; α=89.96(2)°, β=93.28(2)°,γ=90.02(2)°; V= 1.4264 nm³, Z=4, D_c=1.398 g/cm³, R=0.042.In the crystal, two molecules form a dimer with two hydrogen bonds.
